Hi keep going on OFC(Optical Fiber Communication)

1. Optical Fiber Communication
Losses & Measurement Tools

2. Test Equipment
1. OTDR
2. Power Meter
3. VFL
4. Optical Continuity Tester

3. Test Equipment
1.OTDR (Optical time domain Reflectometer)
It can verify splice loss, measure length and find
faults.

4. Handheld OTDR

5. OTDR Output

6. 2.Power Meter
Single-mode/Multimode Loss Test Kit
• Measure true loss of fiber
• Fiber identification
• Certify Fiber for Sale/IRU

7. 3.VFL(Visual Fault Locator)
Visual fault locator testing devices use for
• to trace optical fibers,
• check fiber continuity and
• find faults such as breaks, bad splices and
tight, sharp bends in fiber optic cable.

8. VFL uses powerful visible light at the 360 to
670nm wavelength injecting to a fiber to visually
and directly locate the faults in fiber optic cable.
• Standard 450nm
The most popular visual fault locators are pen
shape VFL and hand-held VFL, which are showed
in the following picture respectively.

12. Fiber Optic Connectors
SC (Subscriber Connector)
• Square connector
• Push-Pull snap
LC (Lucent/little connector)
• Small high density
• Snap fit
• Used on Lasers(XFP/SFP)
ST (Straight Tip)
• Round
• Twist lock
• Common in Sub Stations
UPC (Ultra Physical Contact)polish style of fiber optic ferrules
• Standard for most applications
APC (Angled Physical Contact)
• Has Lower lightwave reflectance
• Used in RF optical applications

14. Fiber Optic Installation

15. Installation Checklist
Pre-install checklist:
• PWD Permission
• Contractor Availability
• Worker Health

16. Before starting the install:
• All permits available for inspection
• Sites prepared, power available
• All components on site, inspected, 24-hour
security arranged if necessary Contractor
available
• Relevant personnel notified
• Safety rules posted on the job site(s) and
reviewed with all supervisors and installation
personnel

17. During The Installation:
• Inspect workmanship at every step
• Daily review of process, progress, test data
• Immediate notification and solution of
problems, shortages, etc.

18. After completion of cable plant
installation:
• Inspect workmanship
• Review test data on cable plant
• Set up and test communications system
• Update and complete documentation
• Update and complete restoration plan
Store restoration plan, documentation,
components, etc.

22. • Microtrenching
Digging up roadways to install cables has been
used in the past but often leads to complaints
about the condition of the road once the
cable has been installed.

23. HDD(Horizontal directional digging)

24. Fiber installation Method
• There are two major types:-
1. Pulling Methods
2. Blowing methods

25. Pulling
• Traditionally fibre optic cables were pulled
through cable ducts in the same way as other
cables, via a winch line.

26. Blowing method

27. Blowing Methods Types
• High Air Speed Blowing
• Air-Assist
• Push/Pull Installation
• Air Blown Cable
• Cable Jetting

28. Air Blowing System
The force in air blowing first comes from a
mechanical device which pushes the cable; and
second, from the force of moving air on the
cable jacket, or alternatively, the force of air on a
piston, missile, or carrier at the front end of the
cable.
